# Physics of Paintball

Hey,

I have a report/presentation to do on the physics of paintball. Can you give me suggestions on what to write about and how to present it. Thanks

Some topics which may apply,
1. Projectile motion
2. Collisions
3. Air pressure

Consider how each of these topics are related to Paintball, do a bit of research on them, then but it together.

BTW: On of the general rules of the forum is that we do not do your homework. Show us what you have, and where you are stuck then we can help you over the rough spots. I have given you some very general topics, it is your job to write your report.

Paintballs come in various "hardness", so some splat easily and some don't splat at all.

I would speak on the momentum of them, in terms of this hardness. Furthermore mentioning the force of the gun and how it could be decreased or increased so that a harder ball would cause the same force on the body as a softer one, and vice versa.

1. Projectile motion
2. Laws of dynamic motion
3. Momentum
4. energy theory (power of the gun comes from?)

Those would be the prime subjects!

Carefull with this guys advice, momentum is mass*Velocity. The "hardness" of the ball has nothing to do with it.
Again do some research on the physics of projectiles.

Once again, be careful of this, Force= mass* acceleration, again hardness or softness of the ball does not enter into it.

Of course the hardness has something to do with it.

Common knowledge makes it obvious.

The only thing that effects momentum is speed and mass.

All that effects force is mass and acceleration.

Now the hardness may effect the speed but once the ball is flying its momentum is determined by its speed and mass.

Maybe you are using the wrong word?

energy

if a projectile splats readily on impact
part of its kinetic energy is converted to its own dispersion
if it does not splat then essentially all
of its kinetic energy is delivered to your body or whatever absorbs the impact
